= Stanley Deser
{c}
<Stanley Deser>, with <Richard Arnowitt> and <Charles W. Misner>, developed the canonical dynamics of <general relativity>. The formulation separates physical evolution from coordinate freedom and makes the constraint structure explicit.<The Dynamics of General Relativity by Richard Arnowitt and others>[Canonical reduction and gravitational constraints]{ref}
The distinction matters when counting degrees of freedom: the number of written metric components is larger than the number of independently propagating gravitational modes.
